  • Patent number: 10400485
    Abstract: A drive control apparatus includes an opening-and-closing body. A first driver drives the opening-and-closing body in a closing direction. A second driver moves the opening-and-closing body from a half-latched position to a fully-latched position. A fully-latched detector detects that the opening-and-closing body has reached the fully-latched position. A stop detector detects whether a predetermined stopping condition has been satisfied for stopping the driving of the opening-and-closing body in the closing direction. A drive controller is configured to drive the opening-and-closing body via the first driver in the closing direction. Upon the fully-latched detector detecting that the opening-and-closing body has reached the fully-latched position, the second driver ends operation and the first driver continues to drive the opening-and-closing body in the closing direction until the stop detector detects that the predetermined stopping condition is satisfied.

  • Publication number: 20190234119
    Abstract: To provide an emergency release device of a lock system capable of opening a trunk lid using an emergency release lever, the emergency release lever is manipulatable between a first position for placing a pawl in an engagement position and a second position for placing the pawl in a non-engagement position from the inner side of the trunk and is biased toward the first position. An anti-return mechanism prevents the emergency release lever from returning from the second position to the first position when the emergency release lever is manipulated from the first position to the second position.

  • Patent number: 10293730
    Abstract: A seat reclining apparatus includes: first and second reclining lock mechanisms that operate in a locked state and an unlocked state, where the locked state prevents a seat back from tilting and the unlocked state allows the tilting; a first rotation member that rotates toward an unlocking direction integrally with the shaft body to change the first reclining lock mechanism from the locked state to the unlocked state; and a second rotation member that is operated to rotate by an operation member toward the unlocking direction to change the second reclining lock mechanism from the locked state to the unlocked state via a cable. When the operation member is operated, the second rotation member rotates from the locking position toward the unlocking direction by a predetermined amount, subsequently transmits a rotation force to the first rotation member toward the unlocking direction via an interlocking portion.
